2 COMPUTATIONAL SCIENCE & ENGINEERING Leading-edge science and engineering depend on advanced computing for understanding, prediction, and control. In response to these needs, the field of computational science and engineering (CS&E) is evolving rapidly, to the point that it is now widely considered to be a new discipline by itself and a third pillar of the scientific enterprise, a peer alongside theory and physical experiment. CS&E is unique in that it enables progress in virtually all other disciplines by providing windows of discovery when traditional means of research reach their limits. - Editorial, SISC Special Issue on CS&E (2007)

3 CS&E IN MATHEMATICS View: Max Gunzburger

4 CS&E PIPELINE IN INFORMATICS Data analysis Pattern recognition, statistics, signal processing, parameter identification Simulation Modeling approaches Physics, dynamical systems, continuums mechanics, fluid mechanics,... Differential equations, integral equations, statistics, geometry, Model reduction, uncertainty quantification Discretisation techniques Approximation theory, functional analysis Numerical analysis of PDEs and ODEs Meshing, error estimators, adaptivity Algebraic solutions (Linear algebra, iterative methods, multigrid) Optimization, steering, inverse problems Implementations Hardware architecture Parallel numerical algorithm Software engineering for simulation tasks, efficient programming Post-processing Visualization, computer graphics Computational steering View: Uli Rüde

5 CS&E IN ENGINEERING Seldom have so many independent studies been in such agreement: simulation is a key element for achieving progress in engineering and science. Authors: J. Oden, T. Belytschko, J. Fisch, T. Hughes, C. Johnson, D. Keyes, A. Laub, L. Petzold, D. Srlovitz, S. Yip

6 EDUCATION IN CS&E A CS&E-student should be an expert in developing (and using) computational methods and not necessarily an expert regarding a specific application. Methods shall be applicable to several applications application-spanning methodological competence. This is the main difference between a CS&E student and a specialist (e.g. engineer) The focus shall be therefore on the modeling and simulation techniques (and natural science). This is the difference between CS&E students and students in mathematics or computer science. Math and computer science need to be linked together in an interdisciplinary sense.

7 CS&E ACTIVITIES EXIST International Association of Computational Mechanics (IACM) and its German section (GACM), Arbeitsgemeinschaft Simulation (ASIM), which is an activity group of the Gesellschaft Informatik (GI), As part of the excellence initiative: Cluster of Excellence for Simulation Technology (SimTech) and graduate schools at Aachen and Darmstadt, DFG Schwerpunktprogramm (priority program) on ExaScale Software, and SIAM Activity Group CSE.

8 CS&E CS&E is in-between mathematics, computer science and the respective application. Despite the existing national and international momentum, there exists no coordinated activity group that scientifically represents the full spectrum of, CS&E in Germany. GAMM has traditionally strong links to mathematics and many CS&E relevant application fields. The GAMM has also strong links to the computer sciences, in particular with high performance computing, parallel algorithms, visualization and data analysis.

9 CS&E AS PART OF THE GAMM Submitted an application to the board of the GAMM to establish an activity group Computational Science and Engineering This application was approved at the last board meeting of the GAMM in Darmstadt in March Kick-off meeting

10 AIMS OF THE GAMM FA CS&E The activity group on CS&E shall represent the subject itself and provide a forum to discuss the interests of research and education concerning CS&E. To adequately represent the interdisciplinary nature of CS&E towards universities and research institutions and to promote the necessary link between mathematics, mechanics, physics, computer science, natural and engineering sciences.

11 AIMS OF THE KICK-OFF MEETING Discuss and define CS&E from different point of views (engineering, mathematics, computer science, high performance computing, industry,...). Discuss research and funding environment CS&E in education Establish networking links Provide an international perspective on CS&E Constitute the GAMM activity group on CS&E Discuss further activities of the GAMM FA CS&E
